MOM

The MOM function returns the component comp of the total Linear Momentum of all Bodies with mass in a model. This includes PART (PLANAR and 3D), FE_PART (2D and 3D), FLEX_BODY, and POINT_MASS. The computed Momentum is returned in Global coordinates.

Format

MOM (comp)

Arguments

 
comp
An integer value that specifies the component of the MOM to be returned.
1 - x-component of the total Linear Momentum
2 - y-component of the total Linear Momentum
3 - z-component of the total Linear Momentum

Examples

REQUEST/1
, F2= MOM(1)/
, F3= MOM(2)/
, F4= MOM(3)
This REQUEST statement outputs the x-, y- and z-components of the total Linear Momentum of all Bodies with mass. The Momentum is in Global coordinates.
 
Caution:  
The MOM function should only be used in REQUEST and SENSOR statements.
